h) ax + a + bx + b =

Answer 1

C)
= 2a + 2n + ax + nx
= 2.(a + n) + x.(a + n)
= (a + n).(2 + x)

***************************************
d)
= ax + 5bx + ay + 5by
= x.(a + 5b) + y.(a + 5b)
= (a + 5b).(x + y)

******************************
e)
= 3a – 3b + ax – bx
= 3.(a - b) + x.(a - b)
= (a - b).(3 + x)

******************************
f)
= 7ax – 7a + bx – b 
= 7a.(x - 1) + b.(x - 1)
= (x - 1).(7a + b)

*****************************
g)
= 2x – 2 + yx – y 
= 2.(x - 1) + y.(x - 1)
= (x - 1).(y + 2)

******************************
h)
= ax + a + bx + b
= a.(x + 1) + b.(x + 1)
= (x + 1).(a + b)
